 # JEE Advanced 2018: Important Topics To Study In Physics

By Sashikanth

Over 10 lakh students took Joint Entrance Examination (JEE) Main on Apr 8, 2018. After taking JEE Main, we understand that idly waiting for the JEE Main results will be of no use. Hence, we suggested aspirants to focus on other areas that included attempting the state-level entrance examinations besides preparing for JEE Advanced.

JEE Advanced is the next round of the selection process after JEE Main. Only top 2.24 lakh candidates will be shortlisted for taking JEE Advanced, which will be held on May 20, 2018. The figure seems to be daunting but stay focused till you get the JEE Main results.

We hope many students have initiated the JEE Advanced preparations after verifying the JEE Main answer key. Physics in JEE Advanced is not a hard nut to crack, if you have devoted enough time for your preparations. Here are some of the tips and important topics for the physics section in JEE Advanced.

## JEE Advanced 2018 Important Topics In Physics

• General: Units and dimensions, methods of measurement, experiments based on using vernier calipers and screw gauge (micrometer), simple pendulum, Young's modulus by Searle's method, calorimeter, speed of sound using resonance column, Ohm's law using voltmeter and ammeter
• Mechanics: Relative velocity, Newton's laws of motion, inertial and uniformly accelerated frames of reference, kinetic and potential energy, work and power, conservation of linear momentum, elastic and inelastic collisions, law of gravitation, motion of planets and satellites in circular orbits, escape velocity, angular momentum, simple harmonic motions, Hooke's law, Pascal's law, Buoyancy, surface energy and surface tension, doppler effect Bernoulli's theorem and its applications
• Thermal Physics: Calorimetry, Newton's law of cooling, ideal gas laws, first law of thermodynamics and its applications, Kirchhoff's law, Wien's displacement law and Stefan's law
• Electricity And Magnetism: Coulomb's law, flux of electric field, Gauss's law and its application, Ohm's law, Kirchhoff's laws and simple applications, Biot-Savart's law and Ampere's law, galvanometer, Faraday's law and Lenz's law
• Optics: Total internal reflection, combinations of mirrors and thin lenses, magnification, Huygen's principle and interference limited to Young's double-slit experiment
• Modern Physics: Atomic nucleus, law of radioactive decay, fission and fusion processes, energy calculation in these processes, photoelectric effect, Bohr's theory of hydrogen-like atoms, Moseley's law and de Broglie wavelength of matter waves

## Number Of Questions

After considering the 2017 JEE Advanced question paper, around 12 questions were asked from the mechanics unit. If you are strong in this unit, half of the job is done. A total of eight questions are from the electrodynamics and six questions from modern physics. Aspirants who are preparing for JEE Advanced are suggested to keep these figures in mind while preparing.

## JEE Advanced Physics Tips

• The current electricity unit is very important. If you are strong in Kirchoff's law problems, you can score well.
• Never ignore radioactive decay, which will be helpful in solving many problems.
• Most of the kinematics questions will be asked based on the basic concepts.
• More than three questions will be based on the formulae. So read them thoroughly.
• One can expect direct questions from simple harmonic motion.
